MAINTENANCE
Water heaters are heat producing appliances. To avoid damage or injury, do not store
materials against the water heater or vent-air intake system. Use proper care to avoid
unnecessary contact (especially by children) with the water heater and vent-air intake
system. UNDER NO CIRCUMSTANCES MUST FLAMMABLE MATERIALS, SUCH
AS GASOLINE OR PAINT THINNER BE USED OR STORED IN THE VICINITY OF
THIS WATER HEATER, VENT-AIR INTAKE SYSTEM OR IN ANY LOCATION
FROM WHICH FUMES COULD REACH THE WATER HEATER OR VENT-AIR
INTAKE SYSTEM.
The following maintenance should be performed by a qualified service technician at
the minimum periodic intervals suggested below. In some installations the
maintenance interval may be more frequent depending on upon the amount of use
and the operating conditions of the water heater. Regular inspection and
maintenance of the water heater and vent-air intake system will help to insure safe
and reliable operation.
1. Annually check the operation of the thermostat.
2. The flow of combustion and ventilation air MUST NOT be restricted. Annually
inspect the direct vent-air intake terminal to insure it is not blocked or damaged.
Clear the direct vent-air intake terminal openings of any dirt, dust, or other
restrictions. WARNING! Certain areas of the direct vent-air intake terminal are
HOT.
3. Annually inspect the vent-air intake system to insure that all components are
securely fastened and all joints and seams are properly sealed.
4. At all times keep the water heater area clear and free from combustible
materials, gasoline and other flammable vapors and liquids.
5. Bi-annually conduct a visual check of the main and pilot burner flames to
determine that they are burning properly. See “BURNER FLAME CHECKS.”
